A first set of fixed, parallel, perforated metal tubes (5), inside the mold (4), possesses lateral holes (9) for the passage of a second set of perforated or non-perforated metal tubes (10) firmly fixed to a movable external support (11), passing through one of the short walls of the steam chamber (1) and capable of moving perpendicular to the tubes (5) of the first set, passing through the latter. The chamber (1) is provided with inlet valves (13) for the partially expanded synthetic material, an inlet (14) for steam and an inlet (15) for a cooling fluid.

Abstract: Apparatus and method of mixing a comminuted food material and a liquid to form a solid food article includes a rotary measuring wheel for dispensing the food material from a storage bin in discrete measured quantities and a rotary peristaltic pump for dispensing the liquid from a storage tank in respective discrete measured quantities. The wheel and pump are coaxially joined for unitary dispensing rotation and a micro-processor controlled arrangement actuates and deactuates a predetermined number of revolutions thereof to effect simultaneous dispensing respectively sequentially of respective predetermined pluralities of the discrete measured quantities of food material and liquid. A chute arrangement receives the dispensed quantities and directs the food material gravitationally downwardly through a central passageway while directing the liquid through apertures arranged to sprayingly emit the liquid convergingly toward the gravitational path of the food material.

Abstract: The hot pressing of ceramic material in dies forming a column, each die being shaped to interfit and cooperate with adjacent dies to cause densification of ceramic material within the dies when pressure is applied to the column. The column of dies is passed intermittently through a fixed, heated zone and pressure is applied to the column intermittently to move the dies through the heated zone and, as a separate step, to compress the column and cause densification of ceramic material in the dies.

Abstract: A device for loading a dosage layer of material, preferably concrete, at a laying-down position for manufacturing tiles and the like comprising, a conveyor for supplying a continuous layer of the material, a bell having a diaphragm and edges surrounding the diaphragm defining a dosage space for receiving a dosage layer of the material and a driving unit for driving the bell to move it into engagement with the continuous layer on the conveyor to receive a dosage layer of material in the dosage space. A suction pump is connected to the interior of the bell for establishing an underpressure therein so that the dosage layer of material is held by suction in the dosage space. A plurality of the bells may be provided on a single turret so that one dosage layer of material is being drawn up while another dosage layer of material is being laid down at another location.

Abstract: An arrangement for filling an upwardly open cavity of a mold with bulk material includes a feeding receptacle which has an open bottom and is mounted for relative movement along the mold from a receiving position in which bulk material is introduced thereinto, towards a discharging position in which the bulk material is discharged from the feeding receptacle through its open bottom.

Abstract: Equipment for filling molds with colored mortars to obtain cement tiles or the like, having a pattern, includes a filling station having a pair of mold partitions which can be raised and lowered with respect to the molds and which can be rotated horizontally through 180.degree. between a first position, in which a partitioned unit is aligned with a mold, which may be a multiple mold, to be filled, and a second position in which a mold unit is in an outer washing position. A batching unit is raisable and lowerable on the mold, and includes several small tanks for the colored mortars, discharge tubes emerging from the bottoms of the tanks, and batching cups that can slide in a sealed manner along the tubes and which are moved along the tubes between a position submerged in the mortar of the small tanks and a raised and emergent position, in which the mortar contained therein is discharged into the respective tube.

Abstract: The instant invention is directed to a mixing head for mixing reactants preferably for the production of foam. The mixing head is characterized as having a housing in which an ejector piston is guided, the guide bore of said piston being crossed by a guide bore for a restrictor slide which has a passage for the ejector piston, an outlet element being situated immediately subjacent to said passage, and, in the most preferable embodiment, the restrictor slide and ejector piston being connected to a control device.

Abstract: An improvement in the generation of foam from a mixture of foam-forming material in a structure having a preferred configuration. Conveying means are used to convey the structure along a horizontal path. A plurality of foam gun heads are mounted in spaced relationship to each other over and transverse to said horizontal path. Each foam gun head includes a foam dispensing outlet and valve means for controlling the discharges of the foam-forming materials therefrom. First, sensing means are provided upstream of the foam dispensing outlets for sensing the passage of the structure thereby. A plurality of second sensing means are positioned upstream of the foam dispensing outlets in spaced relationship to each other in a direction transverse to the horizontal path, each one of the second sensing means being associated with one foam gun head for sensing the presence of the structure in a vertical direction.
